The siblings' hands roam, exploring each other's bodies with a hunger they've long suppressed. The sister guides her brother's hand to her wet pussy, encouraging him to finger her, to make her cum. She grinds her ass against his cock, feeling it harden even more. They're both breathless, their hearts pounding, as they succumb to their taboo desires. The blanket rustles with their movements, a symphony of their shared pleasure, as they give in to the forbidden passion beneath the cover.
